In a recent poll, 1051 randomly selected adults were asked whether they approve of labor unions; 64% said yes. a. In 1936, about 68% of adults approved of labor unions. At the 5% significance level, do the data provide sufficient evidence to conclude that the percentage of adults who approve of labor unions has decreased since 1936? b. In 1963, roughly 67% of adults approved of labor unions. At the 5% significance level, do the data provide sufficient evidence to conclude that the percentage of adults who approve of labor unions has decreased since 1963? a. What are the hypotheses for the one-proportion z-test? Ho: P=H₂: P (Type integers or decimals.) What is the test statistic? z= (Round to two decimal places as needed.) Identify the P-value.
